Ethnobotany of the Aegadian Islands: safeguarding biocultural refugia in the Mediterranean
2021
Abstract Background The Aegadian Islands are located west of Trapani, Sicily. Once the site of bountiful tuna fisheries and fruit orchards (plums, peaches, apricots), grapevines, prickly pears, and grains, the local economy is now based on tourism, and many traditional agricultural and maritime practices have been abandoned. In this study, we aimed to evaluate the state of traditional ecological knowledge (TEK) concerning the use of wild and cultivated plants and fungi for human health, food, maritime, and agricultural purposes on the islands of Levanzo, Favignana, and Marettimo and compare present-day practices with those documented in the past. Methods In-depth semi-structured interviews …
Spatial variations in Ba/Cashell fingerprints of Glycymeris pilosa along the eastern Adriatic Sea
2020
Abstract The long living Glycymeris pilosa bivalve is an interesting target species for the sclerochronological research in the Mediterranean Sea. In this study, Ba/Cashell and Mg/Cashell variations were studied along the coast of the eastern Adriatic Sea. Specimens were collected alive by SCUBA and skin diving during several occasions in 2014, 2015 and 2016 from five sites including Pag, Pasman Channel, Cetina, Živogosce and Drace. Element-to-Cashell ratios were measured by LA-ICP-MS in line scan mode in three specimens of each site, ranging in age from 7 to 21. In addition, chemical analysis was conducted on three ontogenetically older specimens (68-97 years-old) from Drace. Mg/Cashell an…
New distribution and taxonomic information on Callitriche (Plantaginaceae) in the Mediterranean region
2017
This article presents new records of water-starworts (Callitriche sp. pl.) from the Mediterranean basin, resulting from review of herbarium specimens and field work. Callitriche brutia var. naftolskyi is stated as a new combination and confirmed from Greece (Lesvos and Milos), Israel, Italy (Sardinia and Sicily), Libya, Morocco and Syria; C. lusitanica from Greece (Lesvos), Israel and Italy (Sardinia and Sicily); C. brutia var. brutia has been known from Greece for some time but is confirmed from Lesvos and Milos; C. obtusangula and C. truncata subsp. truncata are both confirmed from Sardinia and Sicily, while the latter is also confirmed from Syria. Callitriche lenisulca and C. stagnalis a…
Mycotheca of Edible and Medicinal Mushrooms at Herbarium SAF as a Potential Source of Nutraceuticals and Cultivated Mushrooms
2018
Basidiomycetes strains (n = 39) belonging to 9 genera in 8 families are kept in the mycotheca of the Department of Agricultural, Food and Forest Sciences at the University of Palermo (Palermo, Italy). All of the strains are medicinal mushrooms, and some are of great commercial and nutraceutical interest.
Gene flow and population admixture as the primary post-invasion processes in common ragweed (Ambrosia artemisiifolia) populations in France
2010
*An improved inference of the evolutionary history of invasive species may be achieved by analyzing the genetic variation and population differentiation of recently established populations and their ancestral (historical) populations. Employing this approach, we investigated the role of gene flow in the post-invasion evolution of common ragweed (Ambrosia artemisiifolia). *Using eight microsatellite loci, we compared genetic diversity and structure among nine pairs of historical and recent populations in France. Historical populations were reconstructed from herbarium specimens dated from the late 19th to early 20th century, whereas recent populations were collected within the last 5 yr. *Re…

The first confirmed population of the globally endangered Pilularia minuta (Marsileaceae) in Sicily
2016
Based on a recent collection made by the authors, the presence of the endangered Pilularia minuta Durieu in Sicily (Italy) is confirmed. Critical review of relevant literature and herbarium specimens suggests that the only previous report for the island, made in 1887, can, fairly confidently, be considered to be the result of a misidentification. There is an urgent need to protect the wetland at Anguillara (near Calatafimi), where the species was found.
Taxonomic investigations on Psoralea palaestina (Fabaceae), a critical species of Mediterranean flora
2016
Psoralea palaestina is a critical and unappreciated species described from Palestinian territories, and currently treated as synonym of P. bituminosa, nowadays known as Bituminaria bituminosa. Nomenclatural investigations allowed to ascertain that it was validly described for the first time by Bassi (1768) and not by Gouan (1773), as previously thought. Extensive taxonomic investigations revealed that this very peculiar legume is morphologically well differentiated from the other allied known species. Therefore, it has to be properly treated at specific level and transferred to the genus Bituminaria, thus proposing a new combination: Bituminaria palaestina. Based on literature, herbarium an…
Integrative taxonomy sheds light on an old problem: theUlota crispacomplex (Orthotrichaceae, Musci)
2016
The combined use of morphological and molecular analyses has been proven to be useful in resolving taxonomic complexes with hidden diversity. In bryology, however, integrative taxonomy has rarely been employed to revisit relevant old, unresolved problems. One of these classical controversies is whether the Ulota crispa complex comprises one or three species. To elucidate this, an exhaustive morphological revision, based on numerous herbarium and fresh specimens from most of the Holarctic areas in which U. crispa has been reported, and molecular analyses, using one nuclear (ITS2) and three plastid (trnG, trnL-trnF, atpB-rbcL) loci on a selection of representative specimens, have been perform…
The naming and typification of the breadfruit, Artocarpus altilis, and breadnut, A. camansi (Moraceae)
2018
The historical background and typification of the widely distributed and highly appreciated breadfruit tree, Artocarpus altilis (≡ Sitodium altile; Moraceae), and breadnut, A.camansi, is discussed. Sitodium altile is lectotypified selecting a watercolour painting by Sydney Parkinson made in Tahiti in 1769, during James Cook's first voyage around the world (1768–1771) in HMS Endeavour, and preserved at the Natural History Museum of London. A specimen from E. D. Merrill's “illustrative specimens” of Blanco's Philippine plants in the United States National Herbarium is designated as the neotype for A.camansi.
